Definitions

  • the present invention relates to an automotive lumbar support.
  • a lumbar support for an automobile is composed of a main body portion arranged in parallel in a vertical shape and a panel steel having a substantially U-shape when viewed from the front of a seat back by a connecting portion connecting the lower end portions of the main body portion.
  • a base member a planar support member that is constructed so as to cross the base member and that can move up and down, and a control means that can control the amount of protrusion of the planar support member in the front-rear direction.
  • the base member is supported by a substantially S-shaped spring that is suspended between side frames of the seat back, and the upper end of the main body is supported by the lower frame of the seat back.

  • the lower end is disposed below the lower end portion of the planar support member and between the main body portion of the base member and the lower end portion of the planar support member. Since the urging means that urges the part in the direction that it is always lifted is arranged, even if a large load is applied to the lumbar support, the planar support member of the lumbar support will extend along the body part of the base member. It can move downward, absorbs the impact level, does not cause a so-called bottoming out feeling, and improves the feeling of stroke when a large input is made to the seat.
